COMBINED ANIMAL OPERATING TABLE AND SCALE.

Specification of Letters Patent. Patented Jan, 17, 1922 Application filed January 8,1920. Serial No. 350,198.

T 0 all whom it may concern:

Be it'known that I, \Vm'r citizen of the United States, residing at Belleville, in the county of Republic and Stateof Kansas, have invented certain new and useful Improvements in Combined Animal Operating Tablesand Scales, of which the-following is a specification.

This invention relates to veterinaryoperating tables, and the primary objectof the invention is to provide an improved operating table for small animals, such as dogs, cats, pigs, and the like, which is so constructed as topermit the easy placing of the animals in position thereon and prevent movement of the animals after being'placed in position. I:

'Another; obj ect of the invention is the provision of an improveddevice for facilitating the injection of serumsuch as anti-cholera serum in'hogs. In the injection of serum into hogs, a certain amount-of the drug is injected into the animals according to their weight'and infthe 'methodnow employed, the veterinarysurgeon generally guesses the r I weight of thejanimals which often results in too-little or too much serum beinginjected into the animal, thereby preventing the best 7 results from being obtainedfromthe injec- 30 i tion. 1

It .is therefore, another ,object of the in-'.

vention to provide an improved table for hogs and the like having a scale associated thcrcwithso that the exactweight ofthe animals can be readily and quickly determined. A further object of theinvention is the provision of an improved operating table for small animalswhich can be positioned in a horizontal plane or at an angle to, the horizontal thereby facilitating the treatment and operation of certain parts of the animal. A:still further object of the invention is to provide an improved operating table for small animals which can be readily and quickly taken apart or set up, and which will occupy a very small space when in its knocked down position," thereby facilitating the transportation and storingof the same. A still further object of the invention is to provide an improved device of the above character, which is durable andefiicient in .use,fone that is simple and easy'to manufacture, and one which can be placed upon the market at a reasonable cost.

Otherobjects of he invention will appear in the following detailed description,- taken R. .BARNAR a in connection with the drawings, forming a part of this specification, and in which drawlngs: v T

Figure 1 is a perspective view of the improved operating table.

Figure 2 is an enlarged fragmentaryside elevation of the same, showing parts ofthe table in section. I

Figure 3 is a plan view of the animal receiving trough, and

Figure a is an enlarged detail perspective view of the upper end of the tablesupporting standard.

Referring to the drawings, in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the im-' proved operating table, which includes the support B. the animal receiving trough G having the holding means D associated therewith, and the weighing mechanism E.

The support B includes the tripod base 5 havingrthe' upper terminals of the legs .6 thereof flattened as at 7 and positioned in brackets 8 carried by the collar 9secured to the upper end of the central supporting standard 10. The legs 6 arepivotally secured to the brackets 8 by suitable pivot pins 11. j I r The lower end of the central. supporting standard 10 is provided with a collar 12,

ner terminals of the link sections 15 are pivotally connected together, as at 18 and form a knucklejoint. The-central supporting standard 10 is of hollow formation and is provided intermediate its ends with an interior cylindrical stop 19, which isriveted or otherwise secured in position against ac- :cidental displacement as. at 20; The upper end of the hollow standard 10 slidably supports the solid rod 21. having the head 22 formed thereon, which pivotally supports the animal trough C. The 22 is .pro'

vided with an" upwardly extending centrally disposed reduced lug 23,-Which is adaptedto berpositioned in the slot 24c of the supporting bracket 25 for the trough (3; ,The supporting bracket 25 is enlarged intermediate its en'ds so .as 'to prevent Weakeningof the vsa nie'by the opening 24 and the outer ends of. the bracket 25 are provided 'Wltl'l up wardly and outwardly extending oppositely lncll'il'ed arms 26. The supporting trough (1 includes a pair of'a'ngul'ar related side plates 27 which are held in their correct position i by st-ra'pdrons 28,*' which are arranged adjacent totheterminals of the boards or side plates 2 7an'd are secured tothe same by suitable rastening elements 29;" V

The trough is positioned between the v I arms 2 6' 'carried-bythesupportingbracket V and the arms 26 a-re' secured'to the same by suitabldreinovable fastening elements.

' The-animal holding means D for the trough C'include a pair of flexible straps located I] adjacent to the terminals of the side plates,

andthes'e straps extend through aligned slots 3]; and 32 formed in the side plates The slotsf3l which are located adjacent to V 'tl'i'e forivard end of the plate, are inclined I downwardly and inwardly and the strap 30 which isslidably mounted therein is adapted to. engagethe animalsunuzzle; The

' lower terminals ofea-ch one of the straps the lewer end of the slots.

A pointer 46 is secured-as at 47 to the collar 9 and is adapted to cooperate Withjthe graduations on-the dial plate d4 so that the correct read ing maybe obtained. The upper 'rear end of the dial plate 44: is provided with the up Wardly extendingfreduced shank 48, which 1 provides means whereby the dial platecan' readily be secured to the stud 42; g

In operation ofthe improved device, the

V animal'is laid in the trough C and securely strappedtherein'by means of thestraps 30 11 as clearly shoivnin Figure 3 of the drawengages around the animals body adjacent to the'rear endthere'of. The correct' veight can be readily seen by" the" position of the dial plate in relation to the pointrfldG and the amount of se'rum t'o be injectedinto the animal can be r adil ;det rmined. When rings; and as will be seen, one ofthe straps engage the ann'na'ls muzzle While the other it isdesired to operate on the animals; the

trough can be moved atan incline toithe horizontal by removing the pin 38 and-allowing thebracket to svving onits pivot and ride into engagement with the' shoulders ES'Z. V r Theheightofthe trough can be readily down on the standard the 'collars l? adjusted by moving the collar 12 up "or on the legs '6.

F'ro'nithe foregoing description, it can be seen-that an improved operating table is f provided forIhogs jor 'o'therjs'mall animals,

which isfoiexceptionallysimple and durable construction, and which will efiectively hold the hog or other against" movement Weightlof the animal.
